IN everyday life the shaman is not distinguishable from other people except by an occasionally haughty manner, but when he is engaged in communicating with spirits he has to make use of a special dress and special instruments. Of these the most important and the one in most general use is the shaman's drum. It may be said that all over Siberia, where there is a shaman there is also a drum. The drum has the power of transporting the shaman to the superworld and of evoking spirits by its sounds.
